(1) Find the Fourier series of the square-wave function shown below. Note: This signal is even, and has both half and quarter-wave symmetry. This can be used to simplify the calculation of the Fourier coefficients (check out Ch. 16.3). v(t) V m -T-T/20 T/2 T t (2) The above periodic signal with Vm = 0.5л V and T = 10π ms is applied to the circuit shown below 200 mH + 5 μF : 5 ΚΩ Vo (2.1) Please derive the first 3 nonzero terms in the Fourier series that represents the steady- state voltage vo. (2.2) Which frequency component in the input voltage is eliminated from the output voltage? Explain why.
